Definitions
- canals There may be one or more canals according to the type of tooth.
- the pulse of current emitted by the machine acts on the bundle comprising nerves, vein and artery in the canal.
- the bundle of nerves is disintegrated and blood in the vein is coagulated at the same time.
- the whole apparatus is electronically controlled as seen in the block diagram in Fig. 8,
- Output power can be adjusted with button 24 that acts on the circuit 131 .
